Description

Technical Field

[0001] The utility model relates to a disc structure used in agricultural machinery, belonging to the technical field of agricultural machinery. Background Art

[0002] Disc plow is an agricultural tillage machine, which is particularly suitable for tillage operations in complex farmlands with overgrown weeds, upright stems, large soil specific resistance, brick and stone fragments in the soil, etc. The disc plow blade is an important component of the disc plow, a tillage machine with a disc plow body as the working part. The disc is usually a part of a hollow sphere, and its edge is ground with a cutting edge to facilitate cutting grass and entering the soil. The disc is supported solely on the bearing of the plow column, and the disc surface forms an angle with the forward direction and the plumb direction respectively, which are called the deflection angle α and the inclination angle β. Generally, there are 3 to 6 disc plow bodies on a standard disc plow. When working, the unit moves forward, and the disc rolls and cuts into the soil. The soil rises along the concave surface of the disc and is turned and broken by the cooperation of the scraper board. The disc plow is suitable for heavy, dry, stoney, and rooty soil. It does not require frequent sharpening and replacement, has low maintenance costs, and does not form a solid ditch bottom. Although it does not cover the stubble completely, it is beneficial to prevent water loss in arid land and salt return in saline-alkali land.

[0003] The existing disc plow blade structure is a whole arc-shaped disc setting. Such a structure has no separate reinforcement design. When the diameter of the disc surface is large, the strength of its periphery cannot meet the requirements. When in use, there is a risk of breakage, which needs to be improved.
